Have a look into RH-CD:RedHat/base/stage2.img ls usr/bin [ date kill mformat mv rlogin tar anaconda dd killall minfo mzip rm tee basename df less mkdir nc rmdir test bash dirname ln mknod nslookup route touch busybox du losetup mlabel open rpm true cat echo ls mmd pico rpm2cpio tty chattr env lsattr mmount pidof rsh umount chgrp false lsmod mmove ping sed uname chmod find makedevs modprobe pivot_root sh uncpio chown free mattrib more ps sleep uniq chroot ftp mbadblocks mount pump sort uptime chvt grep mcd mpartition pwd stty vi clear gunzip mcopy mrd python swapoff wc cmp gzip md5sum mren python1.5 swapon which collage head mdel mshowfat raidstart sync whoami cp hostname mdeltree mt raidstop syslinux xargs cpio id mdir mtools rcp tac yes cut ifconfig mdu mtype reset tail zcat ls /usr/sbin badblocks e2label hwclock mke2fs mkswap sfdisk chroot fdisk ifconfig mkfs.ext2 modprobe traceroute clock fsck insmod mkfs.ext3 parted tune2fs ddcprobe fsck.ext2 lilo mkfs.msdos probe debugfs fsck.ext3 lsmod mkfs.vfat reiserfsck depmod gnome-pty-helper lspci mkraid rmmod e2fsck hdparm mkdosfs mkreiserfs route As you can see you can use dd and sfdisk. If you need something else you can copy it into the stage2.img (should be linked statically) cu Florian Festi PS.: Is is possible that %pre is run from hdstg1.img/netstg1.img. I'm not shure about that, but they contain the same tools.
